Testing & Results: DNS-323

Network equipment can be pretty, but it's a real letdown if all it does is look good. If it's inexpensive, that just ensures that it's affordable; but doesn't necessary mean anyone will buy it. Even if it's built like a tank and can withstand complete abuse, consumers are not often swayed. No, we are in the age of "perform or get off the stage". That's what we do here at Benchmark Reviews: set the stage and let the product sink or swim.

NAS Testing Methodology

Testing isn't as hard as most might think. Benchmark Reviews has already had the pleasure of testing other NAS devices in the past, so we have some idea what the D-Link DNS-323 should be capable of. The truth is, since I am writing this section after the testing has already occurred, I can admit that we really had no idea the results would come out this far from our past experiences.

Using two test files, one measuring exactly 100 MB (102,400 KB), and another measuring exactly 1 GB (1,240,000 KB), I would make four write transfers to the NAS device under a timed period. The first transfer was ignored, but the following three were averaged. It should be noted that the average was unnecessary since each test was identical. In all tests, the NAS device hard drives were operating in single disk mode, not RAID 0 or 1, which would have influenced overhead or transfer speed.

For my testing, a brand new 3' CAT-6 patch cord was used to connect the NAS device directly to the Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC built into the ABIT AB9 Pro motherboard. For some strange reason, the whole industry is stuck producing brand new cutting-edge products, but package them with sub-standard accessories. D-Link, like all of the others in the industry, is producing Gigabit Ethernet products, but still includes an antiquated CAT-5 patch cable with each product. You don't even get CAT-5e, which was the reigning standard for nearly the past decade, you get something from the early 1990's. But I digress - you probably understand my point.

Test System

Test Equipment

  • QNAP TS-201 SATA Gigabit RAID NAS
  • D-Link DNS-323 SATA RAID Gigabit NAS
  • 3' Catagory-6 Patch Cable
  • Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC
  • Seagate 500GB SATA-II 7200.10 Hard Disk Drives

Results

UPDATE: D-Link has informed Benchmark Reviews that the DNS-323 offers identical performance to their no-frills DNS-321 NAS. Additionally, the DNS-323 has been re-tested against several newer products in our Featured Reviews: Network section.

Ok, so maybe I'm still in shock by what I have been seeing from the QNAP TS-201 versus what I just witnessed from the D-Link DNS-323 SATA RAID Gigabit NAS. After measuring three test transfers of 100 MB and 1 GB files, Here are the write transfer times (with approximate write transfer speed):

  • 100 MB File Transfer Test
    • QNAP TS-201 SATA Gigabit RAID NAS: 12.0 Seconds @ 8.33 MBps
    • D-Link DNS-323 SATA RAID Gigabit NAS: 6.0 Seconds @ 16.66 MBps
  • 1 GB (1024 MB) File Transfer Test
    • QNAP TS-201 SATA Gigabit RAID NAS: 122.0 Seconds @ 8.39 MBps
    • D-Link DNS-323 SATA RAID Gigabit NAS: 63.0 Seconds @ 16.25 MBps

So there you have it: the D-Link DNS-323 SATA RAID Gigabit NAS is clearly an easy winner compared to the QNAP TS-201, posting results nearly twice as fast. But there's more to it than that. Here are the relative results of other NAS devices based on test results based on benchmarks conducted by SmallNetBuilder:

SmallNetBuilder

Like anyone who tests a product, you like to rely on your own results to include in the review. Well, I have done that, but I think that having only two NAS devices on hand puts our readers at a disadvantage. This is where we call upon others who have a more specific focus on particular components. SmallNetBuilder is one such example, which is why you find their benchmark results displayed above for reference and comparison. Even in their benchmark results the D-Link DNS-323 SATA RAID Gigabit NAS offered better throughput than the majority of the competition.

Hi: We bought a DNS 323. Networked to the system. I am trying to check if the info I added into the system is definitely mirrored onto the 2nd hard disk. Is there anyway I can check that?

Tks for your help. Wen

Pull out one of the drives and see if you can still access data.

Hi, I pull out one of the drive and put it back within a moment. Nothing do to this drive. But i can't see the data folders after put it back. This one i configured for RAID0. Is there any other ways to get back my data folders ?

Nope. Since it was RAID-0 on an external device, your data may be lost.
